If the pencil is attached to a string, andthe string is passed over a pulley, it will balanceat the other end of the string a pencil as heavyas itself, or will lift a pencil lighter than same principle applies to water in a a pipe shaped like the inverted letter U,. I WAVED MY HAT IN DELIGHT; THE EXPERIMENT WAS A SUCCESS. It seemed to me that even the dog, Daisy, appreciated the magic. in which the arms are of equal length, is filledwith water, and each end of the pipe is put intoa separate vessel full of water, the downwardpull, or weight, of the liquid in each of the twoarms will balance the other, and, if the water isat the same level in the two vessels, it will remainat that level in both vessels. But if the level ofthe water in one vessel is lower than in the other,since the two vessels are connected with a pipefull of water, the water will run down from thehigher level to the lower. This constitutes whatis called a siphon. A siphon itself has no moremagic about it than a pencil has when it falls, orthan any other similar phenomenon in nature, yetsome of the siphons manifestations seem to benot only magical, but almost incredible.
